Renthal Twinring™ Rear Sprocket - 51 Tooth, Black - Honda 1540-520-51GPBK

The Renthal Twinring™ Rear Sprocket offers a high-performance solution for motorcycle enthusiasts seeking durability and lightweight design. Crafted with an inner ring made from Ultralight™ 7075 T-6 aluminum, the same high-strength material used in Renthal's standard sprockets, this sprocket provides exceptional strength while maintaining minimal weight. The outer ring is constructed from electro-less nickel coated steel, ensuring maximum durability and resistance to wear under demanding riding conditions. The unique manufacturing process involves expanding the steel outer ring at 200°C and fitting it over the aluminum inner ring with an interference fit, complemented by a wave pattern that guarantees a permanent bond for the sprocket's lifespan. This design ensures the sprocket withstands intense side impacts without compromise.
The sprocket features flat socket head screws that add extra strength during impacts and prevent contact with the chain guide, enhancing longevity. Self-cleaning mud grooves between each tooth facilitate dirt removal, reducing chain wear and preventing dirt buildup that can compromise performance. This innovative combination of materials and design not only extends the sprocket's lifespan—lasting up to three times longer than standard all-aluminum options—but also keeps weight significantly lower than all-steel sprockets, optimizing performance and efficiency. Whether for racing or regular use, the Renthal Twinring™ Rear Sprocket delivers reliable, long-lasting durability with minimal weight, making it an excellent upgrade for Honda motorcycle models requiring a 51-tooth rear sprocket.
